Nailor 5000 Series Linear Slot Diffusers provide architectural excellence and outstanding performance flexibility. Available in four different slot opening widths, a range of 1 to 10 slots, and a wide choice of border/frame styles, including a tapered frame that allows for mud in/tape and spackle applications. They feature 'ice tong' style individual pattern controllers in each slot that not only offer a 180° air pattern adjustment, but can also be used to dampen airflow. Designed primarily for ceiling and high sidewall installation, they are eminently suited to, and recommended for, VAV applications. They maintain a tight and stable horizontal air pattern over a wide range of air volumes by utilizing the maximum ceiling Coanda effect. Also commonly used in overhead heating applications, the versatile pattern controllers allow vertical projection of heated air to meet almost any perimeter condition.

The Nailor 4900 Series provides an extruded aluminum bar grille that offers beautiful styling and efficient performance. Linear bar grilles offer a choice of fixed air patterns with 0°, 15° or 30° air deflection, a choice of bar widths and spacing and a wide choice of border/frame style combinations to suit most types of installation including a tapered frame used in mud in/tape and spackle applications. They are available with an optional opposed blade damper for volume control. Linear bar grilles are recommended for supply air applications in floors, window sills, and high sidewall locations. They are not generally suited to ceiling mounted supply applications (other than for directional spot heating or cooling as an air curtain) as they are not designed for horizontal projection from the face.

Nailor 48LL Series Linear Louver (Vane) Diffusers are designed to provide a high capacity, architecturally pleasing linear diffuser that can supply large volumes of air at relatively low sound levels and pressure drops. High quality, extruded aluminum angular discharge louvers are designed to create a stable horizontal air pattern that is tight to the ceiling. Ideal for applications in VAV systems, these diffusers create a strong ceiling coanda effect at typical maximum and minimum flowrates and ensure optimal comfort conditions.

Nailor Series 48LV Linear Vane diffusers are suited for high capacity airflows.  The diffusers are extruded aluminum and available in either a one or two-way pattern. The deflectors vanes are fixed and the core assembly is removeable.
